Cold water acts with extreme slowness upon this Kino, and a 

 dark ruby liquid is the result, with nearly black insoluble phlo- 

 baphenes. The soluble phlobaphenes possess very powerful 

 colouring properties. 



Kino-tannic acid, 35-78 per cent.; insoluble phlobaphenes, 35'8 

 per cent,; soluble in cold water, 55-4 per cent. 



5. Sample sent as E. fissilis. For physical description see 

 previous specimen (No. 4). Cold water yields a dark ruby solu- 

 tion inclining to orange. The Kino dissolves slowly, leaving a 

 residue of phlobaphene almost entirely of a rich red-brown 

 colour, with but a very small proportion of black. 



Kino-tannic acid, 30*59 per cent.; insoluble phlobaphenes, 40*9 

 per cent.; soluble in cold water, 50-1 per cent. 



Following is Dr. Wiesner's description of a sample of E. fissilis 

 Kino examined by him : — " Reddish solution, neutral, remaining 

 clear on cooling, trace of gum-resin. Tough drops, blackish red, 

 zircon-red, translucent, fatty lustre on fracture." 



6. E. mnygdalina, var. No local name. Appears to be scarce. 

 Has a bark something like "Mahogany" (E. rohusta). Cambe- 

 warra, N.S.W., 30th May, 1888. Height, 60-80 ft. ; diam., 2-3 ft. 



The greater portion of the small sample obtained has evidently 

 remained long on the trees. A few freshly exuded drops are of 

 a clear reddish-brown colour ; the remainder is so opaque that its 

 colour by transmitted light can scarcely be determined, though at 

 the edges of some pieces a reddish-brown colour is observed. 

 The general colour by reflected light is Vandyke brown, and the 

 Kino cuts like horn. 



Cold water forms a pale orange-brown solution. It is, however, 

 all but insoluble. Alcohol (B.P. strength of tincture) yields a 

 pale brown liquid, and a granular almost black residue of phloba- 

 phenes.
